LIGHTIN useful Improvement in Lighting-Fixtures,

of which the following is a specification.

My invention relates to that class of fixtures which are termed semi-indirect, and has for its object to provide means to reflect and diffuse some of the direct light rays and illuminate a bowl surroundingthe reflector, which reflects the light rays to the ceilin in this manner, highly increasing the eflectlveness and enhancing the appearance of the fixture as a whole.

My means of accomplishing the foregoing objects, may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a art of this specification, in which:

igure 1 is a vertical sectional view of a fixture embodying my invention.

Fig. 2. is a modified form of the same.

Similar reference numerals refer to similar parts throughout the entire description.

As' shown in Fig. 1, my fixture consists of a difluser ring 3, formed of opal glass and so shaped. as toreceive the direct light rays from the electric light bulb 4, and reflect them in a diflused manner. As clearly shown by the lines in said fi this ring 3 is supported by an annular member 5, which is hung from the ceiling by chains 6, secured to a' canopy 7, of the usual con struction. The member 5, supports a bowl 8, of translucent glass. which surrounds the diffuser ring 3, and a reflector 9, which is carried by the difluser rin 3, and is designed to reflect the rays 0 light from the bulb 4, upwardly to the ceiling whence they are redirected to the working plane. It may be found desirable in some instances to construct the diffuser ring, as shown in Fig. 2

in which it is provided with an inner wall 12 of opal glass and an outer wall 13, which may be vertical or slightly flaring and which has a mirrored surface adapted to receive the difiused light rays and reflect them upon Specification of Letters Patent.

the bowl 8, and thus illuminate it. Wher the reflector 9, is made of glass, it ma in some cases be expedient to blow the di user ring integral with it, in which case it would not be sllvered beyond the point where it joins the diffuser ring. In some cases it may be desirable to omit the annular memher 5, and support the fixture from the diffuser member, thus producing an all glass fixture.

Having described my invention what I regard as new and desire to secure by Letters atent is: r

1. A semi indirect lighting fixture comprising the combination with a source of light, of a reflector adapted to direct the light rays upwardly against the ceiling, a difluser ring of. lass supporting said reflector, said ring eing shaped so as to reflect a portion of the direct rays of light downwardly and diffuse them, an annular member which supports'said difl'user ring, and a translucent glass bowl carried by said member, said bowl surrounding the diffuser ring and reflector.

2. A semi indirect lighting fixture comprising the combination with a source of light, of a reflector adapted to direct the light rays upwardly against the ceiling, a diffuser ring of glass supporting said reflector and formed integral therewith, said ring being shaped so as to reflect a portion of the direct rays of light downwardly and difiuse them, an annular member which supports said difl'user ring, and a translucent glass bowl carried by said member, said bowl surrounding the difl'user ring and reflector.
